Do the numbers of atoms increase or decrease after the chemical reaction?

Yes, in chemical reactions atoms are neither created nor destroyed, nor changed from one kind to another. Those things can only happen in nuclear reactions. Chemistry deals with how atoms combine with one another.

∙ 14y agoThe numbers of each type of atom involved in a chemical reaction are always exactly the same before and after the reaction; only the bonds between the atoms change.

∙ 13y agoyes because energy cannot be created or destroyed so whatever you put into the equation you need to get back out
Wiki User
∙ 11y agoThe total number of atoms before and after a chemical reaction is the same.
Wiki User
∙ 11y agoThere will be neither a change in the number of atoms in a particular element nor a change in the number of overall atoms involved in a chemical reaction.
Wiki User
∙ 8y agoThe number of atoms and their type remain unchanged; only they are rearranged.

∙ 12y agoThey stay the same. Conservation of mass.

In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.
A balanced chemical equation allows you to determine the?
mole ratio ofany two substances in the reaction
In any chemical reaction the quantities that are preserved are?
In any chemical reaction the quantities that are conserved are mass and number of atoms. After the correct formula for a reactant in an equation has been written, the formula should not be changed.
Matter can be created during a chemical reaction?
No new matter is formed after a chemical reaction. In a chemical reaction, the atoms that make up the reactants rearrange to form products with different properties from the reactants. The matter that goes into a chemical reaction is the same matter that comes out, just rearranged. That's why chemical equations must be balanced to show the same numbers of atoms of each element on both sides of the equation.
How do you preserve the law of the conservation of mass in a chemical equation?
By making sure that the same numbers of each type of atom appear on both sides of the balanced equation for the reaction.
What are the similarities and difference between enzymes and chemical catalyst?
so the similarity is that they both speed up the reaction and both have special temperatures they best work at the only difference between them is that enzymes are found in humans and are not made by humans on particular purpose,whereas chemical catalysts are made by people and are not naturaly developed
What does exponential mean?
Numbers that are raised to an exponent either increase or decrease at an extremely fast rate.
How do you find a percentage increase decrease between two numbers?
In order to find the percentage increase and decrease between to numbers are easy. All you have to is subtract the number you start out with to the number it becomes.
What chemical equation has equal numbers of reactant and product atoms?
Any chemical reaction.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What are some ways to describe the relationship between sets of numbers?
by their increase or decrease
What is the difference between multiplying and dividing?
when multiplying the numbers increase unless it is multiplied by a decimal, it will then decrease. when dividing the numbers are divided (splitted) therefor it decreases unless it is divided by a decimal, it will then increase. Decrease means 'gets smaller or less' Increase means 'getting bigger or more'
What does exponentially?
Numbers that are raised to an exponent either increase or decrease at an extremely fast rate.
What indicates the relative numbers of reactants and products in a chemical reaction?
The number of initial chemical compounds (reactants) and the number of final compounds resulted from the reaction (products).
What does not happen in a chemical reaction?
The total numbers of atoms of reactants do not change in products.
In a redox reaction the numbers of some of the elements changes from the reactants to the products?
In a redox reaction the OXIDATION numbers of some of the elements change from the reactants to the products. The numbers of atoms each element never changes in any chemical reaction.
What is an atom inventory?
Is a count of the numbers of atoms of each element in a compound or in a chemical reaction.
